几个指纹增强算法的matlab code(Some codes for fingerprint enhancement)

用c#编写了一套FIR窗口滤波器，其中数据段的提取来自于matlab的混合编程(Written in c# a FIR filter window, including data extracted from the mixture of matlab programming)

获取FFT处理后信号的能量，通过matlab编程实现。(FFT signal processing to obtain energy through matlab programming.)

说明：  MIMO系统信号检测性能误码率，zf，mmse(Bit error rate of signal detection performance in MIMO system)

一个正弦波利用DCT，FFT变换后稀疏化，然后应用压缩感知实现压缩，并有仿真图例说明重构效果。重构算法采用线性规划和OMP算法等，是一个初学CS入门的好例子。(A sine wave using DCT, FFT transform sparse, and then apply compressed sensing to achieve compression, and a legend reconstruction simulation results. Reconstruction algorithm using linear programming and OMP algorithms, is a good example of beginner CS entry.)

比较了基于SE，SR，SS的符号模式CMA算法，仿真表明，SS收敛速度快，但稳态误差大，SR的综合效果最好。(Comparison based on the SE, SR, SS symbolic mode CMA algorithm, simulation results show that SS convergence speed is fast, but steady-state error, the combined effect of SR.)

该程序是通过MATLAB平台作出的修正型平面二次包络蜗杆的仿真图.(The program is made through the MATLAB platform modified Planar Double-Enveloping Worm Simulation Fig.)

传输矩阵计算程序。该程序用于计算膜系(薄膜）的透射反射比例。(tansmission matrix method for calculation of the reflection coefficient and transmissive coefficient of the thin films)

将要分析的数据放在C盘的ELI.xls表的Bay表单中，根据数据多少调整读取范围（修改 b2:f16 此句) 结果有两种，一种是按数据计算权值求出的结果，另一种是参考建议值求出的结果。结果写入C盘的ELI表格，范围要手动根据数据多少调整(The data will be analyzed on the C disk ELI.xls Table Bay form, how much to adjust the data read range (change ' b2: f16' sentence) result, there are two, one is calculated according to weight data the results obtained, the other is the result of reference to find the recommended value. Results written to C drive of the ELI forms, the scope of how much to manually adjust the data)

BFT,正交傅里叶变换，用于检测线性调频斜率的方法。仿真与论文结果一致。(BFT, orthogonal Fourier transform for detecting the slope of the linear frequency modulation method. Simulation results are consistent with the thesis.)
